As part of Zero Trust adoption guidance, this article describes how to protect your organization from cyberattacks and their possible resulting cost and reputation loss. This article is part of the Prevent or reduce business damage from a breach business scenario and focuses on how to create a threat protection and eXtended detection and response (XDR) infrastructure to detect and thwart cyberattacks in progress and minimize the business damage from a breach.

For the elements of the Assume breach Zero Trust guiding principle:

Use analytics to get visibility, drive threat detection, and improve defenses

Described in this article.
Minimize blast radius and segment access

Described in the implement security breach prevention and recovery infrastructure article.
Verify end-to-end encryption

Described in the implement security breach prevention and recovery infrastructure article.

This article assumes that you have already modernized your security posture.

The adoption cycle for implementing threat protection and XDR

This article walks through implementing threat protection and XDR elements of the Prevent or reduce business damage from a breach business scenario using the same lifecycle phases as the Cloud Adoption Framework for Azure—Define strategy, Plan, Ready, Adopt, and Govern and manage—but adapted for Zero Trust.

The following table is an accessible version of the illustration.

Define strategy	Plan	Ready	Adopt	Govern and manage
Outcomes Organizational alignment Strategic goals	Stakeholder team Technical plans Skills readiness	Evaluate Test Pilot	Incrementally implement across your digital estate	Track and measure Monitor and detect Iterate for maturity

Define strategy phase

The Define strategy phase is critical to define and formalize our efforts – it formalizes the "Why?" of this scenario. In this phase, you understand the scenario through business, IT, operational and strategic perspectives. You define the outcomes against which to measure success in the scenario, understanding that security is an incremental and iterative journey.

This article suggests motivations and outcomes that are relevant to many organizations. Use these suggestions to hone the strategy for your organization based on your unique needs.

Motivations for implementing threat protection and XDR

The motivations for implementing threat protection and XDR are straightforward, but different parts of your organization have different incentives for doing this work. The following table summarizes some of these motivations.

Area	Motivations
Business needs	To prevent an impact on or disruption of your organization’s ability to perform normal business activities or being held for ransom, lower the cost of cyber insurance, and prevent regulatory fines.
IT needs	To assist the Security Operations (SecOps) team in creating and maintaining an integrated defense toolset to secure the assets important to the business. Integration and reporting should occur across asset classes and technologies and lower the effort required to provide predictable security outcomes.
Operational needs	To keep your business processes operating through proactive detection and response to attacks in real time.
Strategic needs	Minimize attack damage and costs and maintain your organization’s reputation with customers and partners.

Outcomes for implementing threat protection and XDR

Applying the overall goal of Zero Trust to "never trust, always verify" adds a significant layer of protection to your environment. It’s important to be clear on the outcomes you expect to achieve so that you can strike the right balance of protection for all teams involved. The following table provides suggested objectives and outcomes for implementing threat protection and XDR.

Objective	Outcome
Business outcomes	Threat protection results in minimal costs associated with business disruption, ransom payments, or regulatory fines.
Governance	Threat protection and XDR tools are deployed and SecOps processes are updated for the changing cybersecurity landscape, threats that are encountered, and automation of incident response.
Organizational resilience	Between security breach prevention and recovery and proactive threat protection, your organization can recover from an attack quickly and prevent future attacks of its type.
Security	Threat protection is integrated into your overall security requirements and policies.

Plan phase

Adoption plans convert the principles of Zero Trust strategy into an actionable plan. Your collective teams can use the adoption plan to guide their technical efforts and align them with your organization's business strategy.

The motivations and outcomes you define, together with your business leaders and teams, support the "Why?" for your organization and become the North Star for your strategy. Next comes the technical planning to achieve the objectives.

Technical adoption for implementing threat protection and XDR involves:

Setting up the suite of XDR tools provided by Microsoft to:
- Perform incident response to detect and thwart attacks.
- Proactively hunt for threats.
- Automatically detect and respond to known attacks.
Integrating Microsoft Defender XDR and Microsoft Sentinel.
Defining SecOps processes and procedures for incident response and recovery.

Implementing threat protection and XDR also involves a few related activities, including:

Using the XDR tools to monitor both your business critical and honeypot resources, which you implemented in the security breach prevention and recovery article to lure attackers into showing their presence before they can attack your real resources.
Evolving your SecOps team to be aware of the latest attacks and their methods.

Many organizations can take a four-staged approach to these deployment objectives, summarized in the following table.

Stage 1	Stage 2	Stage 3	Stage 4
Turn on XDR tools: - Defender for Endpoint - Defender for Office 365 - Microsoft Entra ID Protection - Defender for Identity - Defender for Cloud Apps Investigate and respond to threats using Microsoft Defender XDR	Turn on Defender for Cloud Define internal process for SecOps Monitor business critical and honeypot resources with XDR tools	Turn on Defender for IoT Design a Microsoft Sentinel workspace and ingest XDR signals Proactively hunt for threats	Evolve SecOps as a discipline in your organization Leverage automation to reduce load on your SecOps analysts

If this staged approach works for your organization, you can use:

This downloadable PowerPoint slide deck to present and track your progress through these stages and objectives for business leaders and other stakeholders. Here's the slide for this business scenario.
This Excel workbook to assign owners and track your progress for these stages, objectives, and their tasks. Here's the worksheet for this business scenario.

Understand your organization

This recommended staged approach for technical implementation can help give context to the exercise of understanding your organization.

A foundational step in the Zero Trust adoption lifecycle for every business scenario includes taking inventory and determining the current state of your SecOps team. For this business scenario, you need to:

Inventory your current XDR tools, their integration, and the use of automation for incident response.
Review your incident response and recovery procedures and processes.
Review the deployment of your honeypot resources.
Determine the readiness state of your security analysts and whether they need additional skills training or development.

Organizational planning and alignment

The technical work of implementing threat protection and XDR falls your organization’s security team responsible for threat detection and response, which is mostly staffed by frontline security analysts who understand the current threat landscape and can use XDR tools to detect and respond quickly to an attack.

This table summarizes roles that are recommended when building a sponsorship program and project management hierarchy to determine and drive results.

Program leaders and technical owners	Accountability
CISO, CIO, or Director of Data Security	Executive sponsorship
Program lead from Data Security	Drive results and cross-team collaboration
Security Architect	Advise on incident response strategies and practices, XDR tools and infrastructure, and SecOps team evolution
SecOps lead	Implement incident response procedures, XDR infrastructure configuration, incident response automation, and the SecOps discipline in your organization
Security for IT lead	Advise on, implement, and manage business critical and honeypot resources

The PowerPoint deck of resources for this adoption content includes the following slide with a stakeholder view that you can customize for your own organization.

Technical planning and skills readiness

Before you embark on the technical work, Microsoft recommends getting to know the capabilities, how they work together, and best practices for approaching this work.

Because Zero Trust assumes breach, you must prepare for a breach. Adopt a breach response framework based on NIST, ISO 27001, CIS, or MITRE to lower the impact of a breach or cyberattack on your organization.

Cloud adoption plan

An adoption plan is an essential requirement for a successful cloud adoption. Key attributes of a successful adoption plan for implementing threat protection and XDR include:

Strategy and planning are aligned: As you draw up your plans for testing, piloting, and rolling out threat protection and attack recovery capabilities across your on-premises and cloud infrastructure, be sure to revisit your strategy and objectives to ensure your plans are aligned. This includes priority and target milestones of goals for attack detection and response and use of automation.
The plan is iterative: As you start to roll out your plan, you'll learn many things about your XDR environment and the tools you're using. At each stage of your roll-out, revisit your results compared to the objectives and fine tune the plans. For example, this can include revisiting earlier work to fine tune procedures and policies.
Training your SecOps staff is well-planned: From your security architects to your frontline security analysts, everybody is trained to be successful with their threat protection, detection, mitigation, and recovery responsibilities.

For more information from the Cloud Adoption Framework for Azure, see Plan for cloud adoption.

Ready phase

Use the resources listed in this article to prioritize your plan. The work of implementing threat protection and XDR represents one of the layers in your multi-layer Zero Trust deployment strategy.

The staged approach recommended in this article includes cascading the threat protection work in a methodical way across your digital estate. At this phase, revisit these elements of the plan to be sure everything is ready to go:

Your SecOps team is informed that changes to their incident response processes for Microsoft Defender XDR and Microsoft Sentinel are imminent
Your SecOps team is informed of documentation and training resources
Threat hunting procedures and guidelines and automation techniques are ready for use by analysts
Your honeypot resources are in place

The planning phase demonstrated the gap between what you have and where you want to be. Use this phase to implement and test XDR tools and their use. For example, SecOps team leads can:

Enable and use XDR tools for Microsoft Defender XDR to perform incident response on current attacks
Configure the integration of Microsoft Defender XDR and Microsoft Sentinel using data connectors and workspaces
Define or refine the SecOps team procedures and processes
Explore and test threat hunting for proactive identification of threats and automation to detect and recover from known attacks

Adopt phase

Microsoft recommends a cascading, iterative approach to implementing threat protection and XDR. This allows you to refine your strategy and policies as you go to increase the accuracy of the results. There’s no need to wait until one phase is complete before beginning the next. Your results are more effective if you implement elements of each stage if you iterate along the way.

The main elements of your Adopt phase should include:

Making Microsoft Defender XDR part of your ongoing, day-to-day incident response workflow in your SecOps team.
Using the features of Microsoft Sentinel with Microsoft Defender XDR integration.
Implementing automation to address known attacks, freeing up your SecOps team to perform threat hunting, and evolving your team’s discipline to be forward-thinking and prepared for new trends in cyberattacks

Govern and manage phases

Governance of your organization’s ability to detect attacks with a threat protection and XDR infrastructure is an iterative process. By thoughtfully creating your implementation plan and rolling it out across your SecOps team you have created a foundation. Use the following tasks to help you start building your initial governance plan for this foundation.

Objective	Tasks
Track and measure	Assign owners for critical actions and responsibilities such as incident response procedures, threat intelligence gathering and dissemination, and automation maintenance. Create actionable plans with dates and schedules for each action.
Monitor and detect	Manage security threats using Microsoft Defender XDR and Microsoft Sentinel, using automation for common or previous attacks.
Iterate for maturity	Continually reassess risks and the cyberthreat landscape and make changes to SecOps procedures, responsibilities, policies, and priorities.
